New check_jtag_chain(System*): collects TAP pins by PinSpec.function, resolves each to its net, and flags JtagTapIncomplete (a device missing TDI/TDO/TMS/ TCK), JtagBusUnbridged (TMS or TCK not common to every TAP device), and JtagChainBreak (dangling TDO/TDI, chain fan-out, or not a single head->tail daisy chain). Surfaced as a pass in `verify`; AnomalyKind extended. Covered by test_bsdl_check (healthy chain, broken chain + split bus, incomplete TAP). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
